Joe Edwards could make his debut for the Robins when Hull visit Ashton Gate.
Boss Keith Millen's defensive options are stretched to the limit heading into the final game of the season.
Millen has already promoted young James Wilson to the starting line-up in response to injuries to Liam Fontaine, Steven Caulker, Christian Ribeiro and Damion Stewart.
With on-loan Jordan Spence having now been recalled by parent club West Ham, academy product Edwards looks set to get his chance instead of the out-of-favour Nicky Hunt.
Although defender Louis Carey made his long-awaited comeback from injury over Easter, the club captain has yet to fully recover from the effects of a fractured skull and is unlikely to be risked against the Tigers.
Striker Nicky Maynard is still suspended following his red card at Sheffield United, but David James, Martin Woolford, Lee Johnson and David Clarkson are available for recalls.
Hull winger Richard Garcia has been ruled out of his side's last game of the season.
The Australia international was forced off in the Tigers' final home game against Crystal Palace last week after sustaining a knee injury and joins defender Corry Evans, player-coach Nick Barmby as well as goalkeeper Vito Mannone on the sidelines.
Evans, on loan from Manchester United, missed out last week with a hamstring strain and is not ready, Barmby is still struggling with a calf problem that has ruled him out of the last seven games and Mannone, on loan from Arsenal, remains sidelined with a shoulder injury.
Liam Rosenior will play no part as he has medial knee ligament damage, but fellow defender Paul McShane is available after returning from his loan spell at Barnsley and serving a ban.
